BENJAMIN W. FREEMAN, OF CINCENNATI, OHIO, WILLIAM S. HERSCHEL, OF ST. LOUIS, MISSOURI, AND HERBERT E. PATTERSON, OF COLUMBUS, OHIG, ASSIGNORS TO THE LOUIS G. FREEMAN COMPANY, OF CINCENNATI, OHIO, A CORPORATION OF OHIO PROCESS FOR, MARKING AND OEMENTING SHOES Original application filed June 28, 1927,

Our invention relates to processes for marking, gluing, pasting and cementing shoes, and leather goods, and is a divisional application of our application Serial No. 202,107, filed June 28th, 1927, which discloses a preferred type of machine for carrying out our novel process.

, In the art of making shoes, with the many changes in styles of ladies shoes, particularly in which highly ornamented efiects are desired, the making of the uppers often requires much hand labor which it is our desire to minimize.

In making a shoe, for example, which has an ornamental portion attached to the upper the present method of manufacture requires the operator to apply adhesive to the ornamental portion, or to the shoe or to both the portion and the shoe, the application of the portion to the shoe upper and the firm pressing down thereof so that the portion will remain inposition prior to the insertion of the stitches which may later be applied to hold the decoration permanently in position.

It is an object of our process to automatically apply adhesive to the portion of the upper to which the decoration is to be applied. Further in addition to the automatic cementing, it is our object to gauge and thus materially aid in the accurate positioning and aligning of the parts to be cemented together. We further clamp and hold down the work coincidently with the gauging, positioning or aligning of the parts to be attached. 'Vhile we have illustrated in the preferred type of machine, which will be hereinafter described with: which wecarry out our process, a die and gauging device which assists in the attachinent and positioning of a decorative portion to a shoe upper, other modifications in which different types of designs, the placing of ornamental portions in difierent positions on shoe uppers,and the achieving of other types of work may be accomplished by varying the shapes of the dies and gauging and clamping devices.

Broadly it is our object to mark shoe elements in a more satisfactory manner than has heretofore been possible. Previously to the best of our knowledge and belief, no proc- Serial No. 202,107. Divided and this application filed October 18,

Serial ess for marking or cementing has been known in which the work has been held against displacement at the time the marking or cementmg has been done. It is our object to hold down the work to be operated on, thereby preventing the displacement of the work by the dies after the impressing operation. V] hen we cement with a machine such as will be described, the well and feed roller associated therewith is filled with adhesive, but upon removing the adhesive and filling the well with some marking material, designs of predetermined size and shape may be applied to shoe elements in an exceedingly simple manner.

The above and other related objects to which reference will be made during the en suing disclosure we accomplish by carrying out our process in accordance with the plan of operation to which the machine illustrated is adapted.

lVe have shown a machine having a frame 1 with a fixed base plate 2 which is provided with some means for aligning the work positioning plate thereon such as the pins or studs 3 which register with holes or depressions in the work positioning plate. The pressure platen is indicated at 4 having bosses 5 and 6 in which are pivotally mounted the arms 7 and 8 respectively on which the pressure platen is carried. The mechanism for oper ating the pressure platen is preferably by a foot treadle. The arms 8 may be fixedly mounted on a shaft 9 journalled in the machine frame and a gear segment 10 may be mounted on the shaft 9. Another gear segment 11 mounted on a shaft 12 is also journailed in the machine frame and the segment 11 engages the gear segment 10. The gear segment 11 may have an aperture 11a therein in which a stud is secured and the stud may have attached to it, a treadle rod indicated at 11?), actuable by a foot treadle and usually so spring tensioned that with its release the platen will move to elevated position. lVe have not shown the foot treadle attachment as any means for rocking the shaft 9 will serve to move the platen from open to closed position.

We have indicated a handle 15 which will serve for moving the platen from its open to its closed position, although, as noted, I prefer to operate the machine with a foot treadle. The shaft 9 may be provided with a weight 16 which extends out at the back of the machine and tends to counterbalance the weight of the platen 4. The use of a weight is merely a mechanical expedient for counter-balancing the platen and other mechanical means such as springs may be used to accomplish a similar purpose.

Bosses 17 extend out from the rear of the machine in which arms 18 which carry the fountain and feed roller assembly are pivotally mounted. On the arms 18 we have shown a supply hopper 19 having rotatably mounted therein a feed roller 19a. Springs are disposed as indicated at 20, to tension the feed roller and hopper assembly so that it will be resiliently pressed upwardly into engagement with the die carried by the platen 4.

In order to rotate the feed roller at the same rate at which the die engages it, we have provided driving rollers 20a on ends of the shaft 21 which carry he feed roller. The driving rollers 20a during the elevated position of the platen i engage tracks 22 mounted at the side edges of the lower face ofthe platen so that during the initial movement of the platen from its uppermost position, as indicated in Figure 2, until such time as the uppermost end of the tracks are moved out of engagement with the drive rollers the rate of rotation of the feed roller is such that the material from the hopper is evenly distributed on the die.

In order to prevent the feed roller and hopper from springing upwardly at the time when the tracks of the platen disengage the drive rollers and to make the working parts more accessible, we have provided a curved arm 23 mounted on a shaft 24, on which the arms 18 are fixedly mounted. The curved arm 23 carries a roller 2% which, during the upward movement of the platen, is not in engagement with any guiding device but which, when the tracks of the platen disengage the drive rollers, engages a cam groove 25 in the counter-balancing weight 16.

The machine is designed so that the feed roller and hopper may be readily adjusted or removed and so that the platen i will at some stage of its movement be readily accessible for the interchanging of dies carried thereon.

The die on which the material from the hopper is spread is mounted on a die base plate 26 which is removably mounted on the lower side of the platen i. The die plate has a pin 27 extending from it which seats within an aperture 28 in the platen 4 and a locking handle 29 pivotally mounted on the upper surface of the platen has a locking portion 30 which engages a slot in the pin 27 The die plate 26 may be aligned with the platen with suitable registering devices such as the pins 29a which seat within apertures in the platen. The die may be of desired shape and size. We have in our illustrations shown a die which is adapted for use for cementing thin strips such as is indicated at 31 in Figure 9 to the upper shoe element indicated at 32 in Figure 8. The die consists in this instance of a pair of thin plates 33 shaped similarly to the strip 31 and attached to the die base plate with screws 34.

For supporting the work we have provided a detachable assembly having a work supporting plate 35 with apertures 36 which register with the mounting studs 3 of the base plate 2. On the plate 35 we have shown guide strips 37 which are attached to the plate 35. These strips serve as guiding abutments against which the edges of the work to be operated on may be placed. We have indicated in Figure 7 how a shoe element such as we have indicated at 32 may be aligned on the work supporting plate 35. The work, having been positioned, is held in position by the clamping plate 38 which is articulated to the work supporting plate 35, and also preferably has springs 39a which assist in the movement of the clamping plate upwardly into the position indicated in Figures 3 and 5 with the return stroke of the platen. The plate 38 is shown with cut-out portions 39 which correspond with the shape of the piece 31 to be applied and also allow clearance for the guide strips 37.

For moving the clamping plate to-open and closed position, we have shown a curved arm 38a pivotally mounted in bosses 38?). A lower portion of the arm 380 extends down as indicated in Figure 2 so that a foot treadle attachment may be secured in the arm. lVe have indicated a hole 38d in the arm which may be used for attachment to a treadle member by which the clamping plate may be moved from the open position in Figure 2 to the closed position indicated in Figure 10.

After the work is positioned on the supporting plate the clamping plate is brought against the work acting as a hold down plate and it may then be used to position a strip such as we have indicated at 31 which may be inserted in the cut-out portions 39 and thus positioned on the work. The strips may also be positioned with relation to the imprint of the adhesive or marking material on the work without positioning the strip with relation to the cut-out portions. The strips may be pressed against the work by hand, or the dies 33 may be cleaned off and used as pressure plates to hold the strips in firm contact with the work though such a use requires a cleaning off of the dies after each cementing operation and norm-ally the strips may be secured in position by manual pressure.

In order to explain the variations possible in our process, let us assume that we wish to apply a strip 31 such as is indicated in Figure 9 to a shoe upper 32 such as is indicated in Figure 8. lVe have shown two shoe parts on the work supporting plate 35 where they are properly positioned by being moved into engagement with the edges of the guide strips or abutments 37. The clamping plate 38 is then lowered to hold the work in this position. The platen 4 carrying the die base plate 26 is moved from open to closed position. The feed roller 19a during this cycle of movement deposits a layer of adhesive on the dies 33 which is deposited on the work when the dies 33 pass through the cut-out portions 39 in the clamping plate 38. After a layer of adhesive has been applied, the platen is moved back to open position. The adhesive may be applied as a hand operation the operator using a brush and applying the cement or adhesive through the opening 39. The strips or material to be attached to the work are then inserted in the cutout portions 39 and properly positioned on the work. While the clamping plate is still in position on the work the operator may smooth down the strips by extending her fingers through the cut-out portions, or the clamping plate may be allowed to move back to open position and the strips may be positioned on the work subsequently.

If the machine is to be used for marking only and marked impressions of such shape as are shown in the strips 31 are to be applied to the work, the supply hopper is previously filled with the marking material. The work is positioned in a similar manner on the supporting plate and the clamp and platen are moved to closed position as in the formerly described cycle of operations. hen used for marking the feed roller will deposit a coating of marking material on the dies 33, which, as will be apparent, will be transferred to the work when the dies '33 pass through the cut-out portions 39 of the clamp 38. When used for marking the clamping plate need not have the auxiliary usefulness of a positioning plate.

lVe may, instead of proceeding as above outlined, mark work to which previously cemented strips are to be applied. If the strips to be applied have been previously coated with adhesive, the work may be marked and the strips then applied on the marked portions either with or without the clamping plate in position. It will also be practical to hold down work and then apply previously coated strips to the work, using the apertures in the hold down plate to position the applied strips on the work. Dies, such as we have indicated, may then be used to firmly press down the previously applied strips on the work, in which case the material applying roll need not be used.

While the machine which we have describedwill serve other useful purposes in the art it is designed primarily for marking and cementing and positioning work in accordbe apparentthat the use of a machine which i will save much labor and increase the accuracy and neatness of the work done, is preferable.

I Having thus described our invention, what we claim as new and desire to secure by Letters Patent is l. A shoe ornamenting process which consists in applying cement to a shoe part through a perforation in a member with which the part is being held on a support, and then applying to the part, a decorative piece of corresponding shape as the perforation in the member through which the cement has been applied and then pressing the piece against the shoe part with a member corresponding in shape to the decorative piece.

2. A shoe ornamenting process which con sists in positioning a shoe part to be ornamented on a non-yielding flat surfaced support, holding down the shoe part with a perforate member and then causing an ornamentingdie to pass down through the perforation in the hold down member, and ornament the positioned shoe part.

3. A shoe ornamenting process which consists in placing a shoe part on a non-yielding i'iat surfaced support, lowering a member having a perforate surface against the upper face of the part to be ornamented and also lowering a die causing the work engaging edges of the die to pass through the perforation in the plate, whereby the work under the opening in the plate is ornamented, then raising the die and the plate, thereby releasing the work acted upon for removal from the support.

l. The process of making shoes which comprises placing a shoe element on a support having an abutment, accurately aligning the work on said support in a predetermined location for subsequent operations, by reference to the abutment, lowering a mem her having a perforate surface against the shoe element, to clamp the element against the support and hold it in position against the abutment, cementing a portion of said shoe element by applying adhesive through the perforate surface of the member, applying a decorative piece of material through the perforate surface to the shoe element, then raising the clamping member,'thereby releasing the resultant, composite shoe element, for removal from the support.

5. The process of making shoes which comprises placing a shoe element on a support having a work positioning gauge, accurately aligning and positioning the work on said support, in a predetermined location for subsequent operations, by reference to said gauge, lowering a perforated member against the shoe element to. clamp and retain the element in its accurately aligned position, on the support, as determined by the gauge, cementing a portion of said shoe element by application of adhesive through the perforate member, applying an additional shoe element through the perforate member to the adhesive surface, and then raising the perforate member to release the resultant, composite shoe element.

6. The steps in the process of making shoes which consists in placing a shoe element on a support having an abutment, accurately aligning the work, on said support, in a predetermined location for subsequent operations, by reference to the abutment, lowering a member having a perforate surface against the shoe element, to clamp the element against the support and hold it in position against the abutment, applying an ornamentation to said element through said memher, then raising the plate thereby releasing the ornamented shoe element for removal from the support.

7. The process of making shoes which comprises placing a shoe element on a support having an abutment, accurately aligning the work, on said support, in a predetermined location for subsequent operations, by reference to the abutment, lowering a member having a perforate surface against the shoe element, to clam the element against the support and hol it in position against the abutment, applying an impression of a marking material to said element through said member, then raising the member thereby releasing the marked shoe element for removal from the support.

8. A process of making shoes which comprises positioning a shoe part on a non-yielding flat surfaced support, holding down the shoe part with a perforate member, causin a marking die to pass down through the per 0- ration in the hold down member to mark the positioned shoe art, and then releasing said shoe part for su sequent operations.

9. A process of making shoes which consists in placing a shoe part to be treated, on a non-yielding flat surfaced support, lowering a member having a perforate surface against the upper face of the part to be treated and also lowering a die, causing the work engaging edges of the die to pass through the perforation in the plate whereby the work under the opening in the plate is marked, then raising the die and plate, thereby releasing the work acted upon, for removal from the support.
